			OK Marlin...  Here's one for you (or anyone else out there who knows). 
		
		
		
		
		
		
		
		
	
	What is the correct carburetor for the LT-1/M-40 application in the 1970 Nova? The 1970 Z-28 specs call for a Holley 780cfm; either 3972120/4490 (GM part number/Holley LIST number) or 3972122/4554 when the car was ordered with NB-2. Is there any evidence of Holley LIST 4800 ever being used (this is listed as a 1971 application)? Thanks for any feedback you can provide. Regards, Stan Falenski  |
